The Industry standard half brick package series half brick DC-DC power converters. These PAH topology offers high ef ciency (up to 93.5%), High ef ciency: up to 93.5% compact modules measure 2.3 X 2.4 X 0.5 (58 tight line and load regulation, low ripple/noise, and Outstanding thermal performance X 61 X 12.7mm) and offer the industry-standard a fast dynamic load response. A single-board, highly Half Brick footprint. optimized thermal design contributes to the superior Standard baseplate for conduction cooled applications thermal performance. The PAH Series is ideal for power ampli er No output reverse conduction applications, wireless networks, and telecom These half-bricks provide output trim, sense Input to output isolation, 2250Vdc (Basic) applications.
